01Mechanism of Action

Parameter
PTD-DBM
Testagen
Primary target
CXXC5–Dishevelled protein-protein interaction
Testicular tissue; proposed nuclear DNA interaction
Pathway
Inhibit CXXC5 binding to Dishevelled → Release Wnt/β-catenin pathway inhibitionLee 2015Ryu 2023
Nuclear penetration → DNA/oligonucleotide binding → gene expression modulation (bioregulator hypothesis)Fedoreyeva 2011
Downstream effect
Activated Wnt/β-catenin signaling promotes hair follicle regeneration, dermal stem cell activation, reduced myofibroblast differentiation
Proposed support for spermatogenesis and testicular function; mechanistic data limited to nuclear localization and DNA interactionFedoreyeva 2011
Feedback intact?
Not applicable — pathway derepression rather than receptor agonism
Unknown — no HPG axis data
Origin
Engineered fusion: cell-penetrating PTD sequence + Dvl-binding motif targeting CXXC5
Khavinson bioregulator school — isolated from testicular tissue peptide fractions
Antibody development

02Dosage Protocols

Cycle length
10–20 days on, 10–14 days off
Bioregulator tradition uses pulsed cycles; no controlled data.
Route
Subcutaneous
Reconstitution
Sterile water or bacteriostatic saline
Half-life
Unknown — likely minutes (short peptide)

04Side Effects & Safety

05Administration Protocol

Parameter
PTD-DBM
Testagen
1. Wound Healing Protocol (Animal Model)
Pyrogallol-functionalized hyaluronic acid (HA-PG) hydrogel patch loaded with PTD-DBM peptide, applied directly to wound bed. Adhesive hydrogel provides sustained release over multiple days.Lee 2023
Add 1–2 mL sterile or bacteriostatic water to lyophilised vial. Swirl gently; do not shake. Solution should be clear.
2. Hair Regeneration Protocol (Animal Model)
Topical application to scalp or wound site. Precise formulation not disclosed; studies used Cxxc5 knockout or direct peptide application in wound-induced hair neogenesis models.Ryu 2023
Subcutaneous — abdomen or thigh. Rotate sites daily. Use standard insulin syringe (27–31G).
3. Combination Therapy
PTD-DBM + valproic acid (GSK-3β inhibitor) in HA-PG patch showed synergistic effect on scar reduction and regenerative wound healing. VPA enhances Wnt pathway activation downstream.Lee 2023
Morning or evening; no established optimal timing. Anecdotal preference: evening to align with circadian testosterone patterns.
4. Storage & Handling
Not disclosed in available literature. Peptide stability and storage conditions not published.
Lyophilised: room temp, dark. Reconstituted: refrigerate 2–8 °C, use within 14–21 days if bacteriostatic water used.
5. Cycle protocol
10–20 days on, 10–14 days off. Bioregulator tradition uses pulsed exposure; rationale: prevent receptor/pathway desensitisation.
